Nokia 4A0-107 Exam Syllabus Topics:

Topic	Details
Topic 1	Traffic Classification: This section of the exam assesses the capabilities of Service Delivery Specialists and focuses on classifying incoming traffic based on QoS-related packet header fields. It includes configuration techniques for classifying traffic on SAP-ingress and network-ingress points, as well as the precedence rules for matching criteria. The section also introduces default network policies and outlines how traffic classification is managed at the egress point.
Topic 2	Queues and Policers: This part of the exam evaluates the knowledge of IP Network Engineers in handling traffic using queues and policers. It introduces token bucket metering, queue-based traffic shaping, and the concept of Fair Information Rate (FIR). Candidates are expected to understand the process of creating queues and directing traffic to them, differentiating between priority and profile mode queues, and configuring various types of policers. The section also includes buffer management and the use of Weighted Random Early Discard (WRED) techniques, slope policies, and queue groups for traffic redirection.
Topic 3	Introduction to QoS: This section of the exam measures the skills of IP Network Engineers and covers foundational knowledge of Quality of Service (QoS). It includes an overview of different types of traffic behaviors and their requirements, outlines the QoS mission statement, and introduces IntServ and DiffServ models. Candidates are expected to understand customer traffic rate limitations and the application of QoS specifically on Nokia 7750 SR platforms.
Topic 4	Hierarchical Bandwidth Allocation: This module tests the ability of Service Delivery Specialists to implement bandwidth management using hierarchical approaches. It begins with an overview of Class Fair Hierarchical Policing (CFHP), followed by enabling CFHP for both SAP and queue-group policers. It also covers Hierarchical Scheduling (H-QoS), including its activation for queues, policers, and queue groups on SAP and network interfaces. The section ends with a focus on egress port scheduling strategies for standalone and H-QoS-based queues and policers.
